The significance of needle gauge

Wendy Mullins, Registered Nurse in clinical practice

Dear Editors

Consideration has not been given to the significance of the larger
bore needle (23 gauge) affecting the outcome, seperate to the length of
the needle. Surely, to exclude this variable by comparing 25mm x 23 gauge,
25mm x 25 gauge, and 16mm x 25 gauge would possibly clarify the
significance of the larger bore needle rather than assume the longer
length needle as being the sole variant?
